Hi,
How do i lock the bootloader with a custom rom, is it possible without flashing stock firmware?
also, does locking the bootloader erase data?
Thanks
If you lock your bootloader, the bootloader dont erase data, its very simple to lock, you must have adb&fastboot installed on your pc, you put you phone in fastboot mode and you put: fastboot oem lock

I have the XT-1052 version of Moto X and its running the Asia Retail firmware. I had unlocked the bootloader and flashed CM12 but returned to stock rom through this guide http://forum.xda-developers.com/moto-x/general/retail-firmware-uploaded-xt1052-t2976596. I will be selling the device and want to re lock the bootloader. Can i type the ''fastboot oem lock'' command in mfastboot tool and re lock the bootloader? Also, will it erase the whole data on the device?

Yes, fastboot oem lock will lock it, and no it will not wipe data. Only unlocking wipes data.
But you status code will show relocked you can never get status code back to locked once unlocked.

Correct. Whoever has the phone will be able to see the "tamper seal" that shows the bootloader was previously unlocked, but is now locked again.
I would provide whoever you sell the phone to the bootloader unlock code so they can unlock in the future if they so desire. Not sure if they can request the code from Motorola again or not.

I tried it but it asks me to flash the signed images. The link i mentioned above comes with an XML file which dictates the steps RSD should be following, right? So if i upload the XML file can you edit the command line and add the command? I am not an expert in this stuff.
i have relocked flashing manually with fastboot, not sure if you add the oem lock cmd to the xml will work.
fastboot oem lock begin
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash logo logo.bin
fastboot erase userdata
fastboot erase cache
fastboot oem lock

The files that are present in the rom folder are boot.img, fsg.mbn, gpt.bin, logo.bin, motoboot.img, NON-HLOS.bin, recovery.img and system.img. Can you modify the list of commands to add the aditional files. Thanks.
just flashing the above is enough to relock. Flash away

Tool has a revert to stock option. You can also download the latest fastboot image and flash via MIFlash.

will that lock bootloader again?
To lock the bootloader you can either use the tool (which has the option to lock) or do it manually with the commands
Fastboot oem lock
Fastboot flashing lock
And finally
Fastboot flashing lock_critical
Be sure to flash stock before locking the bootloader, otherwise you may end in a bootloop.

You only need to lock the last two if you unlocked them.
I used this two command to unlock
fastboot flashing unlock
fastboot flashing unlocl_critical
So when i want to return to stock
flash stock rom via miflash flsh_all
Then type this
fastboot flashing lock_critical
fastboot flashing lock
fastboot oem lock
Is this the correct one?

But does it lock critical to? Cause I used the following commands:
fastboot flashing unlock
fastboot flashing unlock_critical
So do i need to revert also those two?

if you do fastboot oem lock, it locks both (flash_all_lock does that)
